lc (o 251- 51 The object of my invention is to provide a pipe joint construction for conduits, which, permits immediate access to the interior of the conduit, whereby a portable wedge or stop member may be inserted therein to stop the flow. of materials such as liquids or solid particles through the pipe joint body.

Another object of my invention is to provide a construction which eliminates all objectionable recesses or projections within'the fluidp'assage 'which'would tend to obstruct the normal flow of material therethrough.

Afurthe'r object of my inventionis to provide a construction in which all guide surfaces for supporting the wedge or stop member in sealing position, are placed external of the fluid passage.

A still further object of my invention is to provide a construction which eliminates allm'achine work or gasket sealed members to produce an efiective stop in the flow of materials.

And a still further object of my invention is to provide a pipe joint construction which facilitates the installation of 'a standpipe or chamber communicating with the ground level and stop opening of the pipe joint'body whereby immediate access to the'op'ening, or wedge lodged therein, may be had when desired. v

In order to limit access to the opening or wedge, it is the object of my invention to provide a removable cover for the standpipe or chamber which is secured thereto by any suitable looking means. V p

' With these objects in view, the invention consists in a construction and combination of parts of which a preferred embodiment: is illustrated in the accompanying drawings, wherein:

Figure 1 is an elevational view illustrating a part of my pipe joint in section; and which further shows connecting conduits secured in place. Figure 1 further indicates my removable wedge inserted in place and the means for removing the wedge from the fluid passage. The upper end of the standpipe or chamber has been illustrated in section to show oneembodiment of a lockingmeans therefor.

The invention is carried into effect by providing a pipe joint body member [2, which fromall external appearances resembles a pipe'joint commonly referred to as a T. From the conventional T, the interior of my body member l2 provides this distinction; into the opening, which extends transversely from the'longitudinal openings of the T, is fashioned a guideway I20. for receiving a removable wedge or stop member l5; Referring in particular to Figs. 2, 3and'4 it willtbe noted that guideway [2a assumes a rectangular shaped opening in'the horizontal plane, which in the vertical plane is connected by tapering surfaces lZf extending into'the'fluid passage 11911. It is likewise important to noteithat guideway I211 intersects but one half of the fluid passage 19a, and that the end surfaces |2t thereof are tangent to the bore of the fluid passage lSa.

The elevational section shown in Fig. 3 and k taken along line 33 of Fig. 2 indicates one preferred method of securing conduits l3 and E4 to the main body member l2. These conduits'l3 and I4 may be of tile or any suitable metallic pipe,

and'which, as illustrated, are inserted in the main body portion so that the fluid passage 19a of the pipe joint body I2 registers with the fluid passages l9 and ;l9b of therespective conduits. In assembly. these conduits l3 and Mare located and sealed'by jute "IBor', other suitable-packing tween the conduit bodies". and the pipe joint 12. A vertical standpipe or communicating chamber H is secured to the vertical'opening'bfthe pipe joint body I2 in a similar manner. However, I

am aware that many othersuitable forms of attaching conduits thereto may'beemployed'without departing from the spiri'tof my invention,

material, the joint being "further completed by the packingof cement IT or its equivalent besuch as threaded pipe joints or flanged pipe joints as may be desired for the particular service to which it is applied. The guideway 12a, referred to hereinbefore for admitting and locating the wedge member l5 in the fluid passage l9a, is provided with inclined surfaces I2 which are fashioned to substantially register with the corresponding tapering faces I51) of the wedge member. The guideway lZa, as clearly indicated in Fig. 4, intersects but the upper half of the bore of the fluid passage |9a and thus eliminates any recesses or projections on the lower half of the fluid passage 19a which may tend to interfere with the normal flow of material therethrough or which may become clogged by settling particles.

and thus prevent the proper lodging of the stop member IS in the fluid passage l9a. This feature provides a marked advance in the construction of devices which may be utilized to effect stoppage in the flow of material. Thus the salient feature of my combined pipe joint and. stop unit, is the provision of a smooth wall surface at the bottom of the fluid passage 19a. Since in certain applications materials may rise into the vertical standpipe while the wedge I5 is removed, inclined surfaces l2b, which communicate with the interior opening of the standpipe ill) and the guideway portion IZa, are fashioned to prevent the lodging of material within the standpipe after normal flow has been reestablished through the conduits. These inclined surfaces l2b likewise serve to direct wedge l5 into the guideway l2a thereby greatly facilitating the entrance of the wedge into the guide- Way.

Figs. 5 and 6 deal principally with the construction of the wedge or stop member l5. As illustrated, member l5 consists principally of a. main body web, provided with opposed inclined surfaces I51) and opposed arcuate surfaces l5e which register with the inclined surfaces I21 of the guide member [2a. The upper portion of the wedge is provided with an opening l5a and so located with respect to the inclined surfaces l5b, that it will always remain within the vertical standpipe II when the wedge is properly located in the guideway I2a. The outer edge 150 of the wedge is fashioned so as to conform with the contour of the fluid passage and the tangent projections I21? forming the end surfaces of opening [2a. The solid lines in Figs. 5 and 6 illustrate a preferred shape my wedge assumes in one embodiment of my invention, while the dotdash lines indicate extensions of the surfaces l5b and I50 to increase the area of contact between the wedge l5 and the guideway l2a.

Referring again to Fig. 1, it will be noted that the outer opening of standpipe H is provided with a removable cover member 8. Within the interior of the standpipe H are formed projections Na and lib, projection Ha being adapted to be embraced by a projection 8d of cover member 8. Diametrically opposite these engaged members, is located an eccentric cam in which essentially consists of a single turn of a coarse worm type screw. The eccentric cam member ID is rigidly secured to the round member 9a which in turn is loosely fitted in the cover'member 8.

The upper end of member 9a is fashioned with a pentagon head 9, which necessitates the use of a special wrench in order to rotate the eccentric cam l into or out of engagement with the projection llb. When access to the interior of standpipe H is desired, the special pentagon wrench is applied to the head 9 and rotated until the eccentric cam member ID disengages projection I lb, whereupon cover 8 may be completely removed. While this method of securing the cover member 8 to standpipe II is illustrated as a preferred arrangement, I am aware that other forms of locking devices may be employed without departing from the spirit of my invention.

Fig. 7 illustrates the particular form of tool which is employed to remove the wedge l from the fluid passage. This tool consists of a rod l6 fashioned at its lower end with a hook lBb while its upper end is fashioned with a handle or suitable gripping means indicated as lfia. In Fig.

1 the hook portion lBb isillustrated as engaging the hole l5a of the wedge member I5. Normally the tool l6 does not form a part of my assembly,

and is preferably of such length so as to prevent application of the cover member 8 as long as tool 16 remains in the standpipe II. It is likewise evident that tool I6 is similarly employed to insert the wedge [5 in the guideway portion l2a. As hereinbefore mentioned, wedge member l5 does not normally form a part of my pipe joint, but is assembled therewith only when stoppage in the flow through the fluid passage l9a is desired. While in a preferred embodiment of my invention it is desired to completely remove the wedge l5 and the tool Hi from standpipe l I, when same are not in use, it will be evident to those versed in the art that tool I6 may be of such length so as to permit same to be normally sealed within the standpipe. Similarly I have fashioned wedge [5 so that same can be normally retained within the standpipe II by placing the wedge at right angles to the guideway portion [2a.

One application of my combined pipe joint and stop is for those locations where it is desirable to discontinue the flow of sewage through conduits |3l4 at various seasons of the year, for such reasons as directing the flow of sewage to some other destination, repairs, etc. It should be clearly understood that the combined pipe joint and stop unit herein illustrated, described, and claimed, has a wide and varied application to conduits conveying most any fluid substance or solid particles therein, and wherein it may be desired to discontinue the flow thereof. For illustrative purposes, the invention has been designated as beingapplied to a sewer conduit but it will be clear that the same is equally applicable to irrigation conduits, oil lines, conduits communicating with grain elevators, and many other conduit connecting systems wherein it is desirable to employ a simple and inexpensive unit for discontinuing the flow of materials therein. Therefore I do not wish to limit myself to any specific use, or to the exact form herein shown .and described other than by the appended claim.

I claim:

A pipe joint body characterized by an external construction resembling a pipe joint T and comprising a smooth cylindrical fluid passage connecting the longitudinally opposed openings of said T body except as intersected by a rectangular opening fashioned in the upper half of said cylindrical passage, the sides of said rectangular opening being connected by wall members that angularly project from the periphery of said cylindrical passage and terminate within the angularly disposed opening of said T body; a wedge shape gate member adapted to be inserted through said rectangular opening; the end wall members connecting the shorter sides of said rectangular opening being tangent to the bore of said cylindrical passage at substantially diametrically opposite points and extended upwardly to an elevation above the upper half of said cylindrical passage to form relatively long guide surfaces for locating said wedge shaped gate member, the wall members connecting the longer sides of said rectangular opening being substantially flat and fashioned to join said end wall members throughout their upright length to provide the sole lateral support for said gate mem- 10 her externally of the fluid passage, said wedge and the contour of the lower half of said cylin- V drical fluid passage whereby said gate member is located and supported entirely by said Wall mem-' bers so as to arrest the flow of material through said fluid passage.
